Absolutely. We use a multi-level email spam and virus filtering system using industry standard tools including Amavis, ClamAV, Spamassassin, Vipul's Razor and several RBL's (real-time black-lists).
The primary focus of the system is to identify and disable any email spam and virus before they reach you. Every message is screened through a series of tests and if identified as either spam or a virus is discarded and will never reach your email inbox. The system is intercepting thousands of spam emails and virus every day.
The system has been fined-tuned and is highly accurate. Only extremely occasionally does legitimate email get intercepted. If you suspect you have messages being intercepted by the system which you'd like to receive you can petition us to add an email sender's address to our spam 'whitelist' which will make any email from them exempt from the filtering process.
